SCA1194
The SCA1194 has a diameter of 1194 mm at the spacecraft interface and
utilizes a Marmon clamp separation system. The spacecraft separation
system uses from 8 to 14 pushoff springs to impart both an initial delta
velocity with respect to the launch vehicle and a spacecraft spin rate
about an axis transverse to the launch vehicle longitudinal axis. In
principle, this relative motion is achieved by limiting the stroke of
adjacent springs with respect to the stroke of the opposing springs. In
addition to the pushoff springs, there are two electrical disconnects and a
clampband impulse that participate in the spacecraft separation
dynamics. The major elements of this clampband type adapter are shown
in figure 7-5.
